LAM PBLACK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 497,686, dated May 16, 1893.

Application filed Aprilll, 1892. Serial No. 42 8,696. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL L. RHODES, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Lampblack Machines; and I do hereby declare that the followingspecification, taken in connection with the purpose, and removed from the surface by suitable scrapers ;-the depositing surface and scrapers being moved relatively to each other for this purpose.

My invention consists of a suitable stationary frame-work supporting the carbon deposit plates and suitable tracks or gnideways, and a carriage working on said tracks or guide-ways and carrying the burners from which the lampblack is deposited, and the scrapers which remove the lampblack from the depositing surface. And I also provide an independent auxiliary hopper for each series of the traveling scrapers carried by the carriage, all of which are adapted to deposit into a central trough or main hopper in which the lampblack is collected.

My invention further consists of certain details of construction and in the manner of operating the several parts; automatically operating scraper plates being provided which will scrape in one direction only, and the carriage being moved backward and forward by means of a screw and an internally threaded pulley through which it works.

I will first describe my invention with ref erence to the accompanying drawings and then more particularly point out in the claims what I deem as new therein.

In said drawings:Fignre 1 is a side elevation, part being broken awayand part being in section, of my improved machine. Fig. 2 is an enlarged detail perspective view of the automatic scrapers and operating mechanism for collecting the lampblack in the main trough. Fig. 3 is an enlarged end elevation of the machine, parts being broken away.

Fig. 4 is an enlarged sectional detail view of one of the scrapers and depositing plates. Fig. 5 is a top plan representation, with parts omitted and parts broken away, of two machines constructed according to my invention and operated by the same feed mechai1- ism. Fig. 6 is an enlarged sectional view of the feed pulley.

Like letters of reference indicate the same parts throughout the several views.

The frame-work upon which my machine is built consists of the upright angle-iron posts A, the horizontalbarsorbeams l3, and suitable braces C, all properly secured together by bolts, rivets, or otherwise, so as to form a rigid and strong frame.

D, D, &o., are a series of parallel concave plates arranged longitudinally of the machine and firmly secured to and supported beneath the horizontal bars B by any suitable means. These plates are to form the depositing surfaces for the lampblack and are arranged with their concave faces downward so that they will more readily protect the burners from drafts, and prevent the deposited lampblack from being carried away by the upward draft from the burners.

E, E, are blocks secured to the inner faces of the uprights A a suitable distance below the horizontal beams B, and F, F, are horizontal tracks or ways secured to said blocks and running longitudinally of the machine. The blocks are for the purpose of supporting the tracks away from the uprights so that the wheels or carriage supported thereon will not interfere with the uprights.

The carriage which runs on the tracks F, and supports the burners and scrapers, consists of the cross-beams G formed preferably of angle-iron, and the longitudinal bars G running between and secured to the crossbeams, and consisting preferably of angleiron. At the ends of each of the cross-beams G extends a vertical plate or block H having formed integral with it an outwardly projecting horizontal spindle 1 upon which is journaled a wheel J. The wheels J run on the tracks F and are preferably formed with central circumferential grooves J to fit over the tracks and keep them in place and guide the carriage in its movement.

K, K, K, &c., are several series of burners arranged longitudinally upon the carriage directly under the depositing surfaces. In the machine illustrated in the drawings I have arranged three series in line for each of the seven concave depositing surfaces, which makes twenty one sets or series of burners. Each series of burners is supported at its center by a branch coupling tube K extending vertically from the main cross-branch pipe K which leads from the longitudinal supply pipe running along on one side of the carriage. These burners and conducting tubes are carried by the carriage, and in order to supply them with the fuel tobe burned for formingthe lampblack, I provide a telescopic coupling L between the supply pipe L and the main supplyM. The pipe L telescopesin the coupling L and has a gas-tight joint which allows for the longitudinal movement of the carriage. Or if preferred it is obvious that the supply pipe L could be as conveniently connected with the supply pipeM by means of a flexible conducting tube.

N and N are a pair of narrow vertical plates or guides secured to the opposite ends of each of the cross-beams G adjacent to the wheels J. Each pair of plates N and N are secured in position with a space between them to form a guide for a narrow vertically operating plate 0, as clearly shown in- Fig. 4. The vertically operating plates 0 are joined together in pairs by cross-bars 0 so as to form scraper carrying frames, as clearly shown in Fig 3, that will move in unison.

Upon the cross-bars O are adj ustably secured a series of scrapers O Q which are arranged in proper relation to the concave deposit plates and have their scraping edges shaped so as to fit the concave faces. of said plates. For adj ustably supporting these scrapers on the cross-bar O I provide a series of screw bolts 0 passing through the cross bar and having screw nuts 0, between which screw nuts and the cross-bar the scrapers are clamped. Each scraperis formed with avertical slot through it from its center to its lower edge, which slot works on the screwbolt, and allows the scraper to be raised or lowered on the cross-bar to regulate its contact and operation with the depositing surface. It will be observed that each scraper is independently adjustable on the cross-bar O, and that the whole series on the cross-bar can be raised in unison, by the plates 0. sliding vertically in their guides on the carriage.

Now itis very desirable that the scraping action should be carried on only when the carriage is traveling forward; so that it becomes necessary to provide means for holding the scrapers in scraping contact while the carriage is moving forward and move them out of scraping contact when the carriage is returning. For this purposeI preferably employ the following means:At each side of the carriagelprovide a longitudinally extending movable bar P, provided with notches 19 each of which is formed witha vertical edge esaese wall and an inclined bottom wall for the urpose to be explained. These bars P pass through openings Q through the pair of plates N, N and through slots Q in the vertically moving plates 0, the upper ends of said slots Q resting on the inclined bottom walls of the notches p. As the plates N and N are stationary on the carriage and the lower straight edge of the bar P rests and operates thereon, it willbe observed that the plates 0 will be moved upward by theinclined notches engaging the upper edges of the slots Q when the bars P are moved forward and that said plates will be allowed to move downward when the bars are moved back. The vertical edges of the notches p are for the purpose of limiting the backward movement of the bars.

For moving the bars P relatively to the carriage I provide stationary stops R at the opposite' ends of the machine, against which the projecting ends of the bars P come in contact at the extremes of the movement of the carriage. Now it will be observed that as the carriage is moving forward to the right in the act of scraping, all of the scrapers are held to their work because the highest portion of the upper faces of the rods P are in contact with the upper ends of the slots Q in the plates 0. But at the end of its forward movement the right hand ends of the rods P come in contact with the stop R at the right hand end of the machine and shift the rods to the left until the vertical edges of the notches 19 come in contact with the plates 0, when said plates will have receded to their lowest position in contact with the inclined notches. The machine is then in readiness for the reverse movement which is accom.

plished without any scraping action. At the end of the return movement the bars P are again shifted and the scrapers again moved into contact with the concave plates when the machine is in readiness for its forward movement.

S, S, &c., are a series of narrow hoppers supported from the traveling carriage and having inclined narrow walls. These hoppers each inclose one seriers of scrapers and lead to a common central troughS' from which the lamp black is collected. The top S of this trough S is securely attached to the lower ends of the hoppers S and is carried thereby, suitable openings 8 being formed therethrough for the passage of the lamp black.

T and T are pairs of angle plates secured to the under side of the cover S at intervals, each pair of plates forming a vertical guide in which rests a vertically adjustable scraper plate S formed with an oblong perforation 5 through it.

'U is a longitudinally movable rod formed with notches u in its upper face. This rod U passes through openings t in the angle plates T and the oblong perforations s in the scraper plates S said perforations s resting on the notched portion of the rod.

U are stationary stops formed at the opposite ends of the machine for the projecting ends of the rod U to come in contact with for shifting the rod from one position to the other as in the case with the bar P for controlling the main series of scrapers. By this means I am enabled to provide a series of collecting scrapers which will be down in working contact with the bottom of the trough S when the carriage is on its forward movement, for collecting the lampblack which falls therein from the series of hoppers S. These. collecting scrapers collect all of the lampblack into a suitable receptacle, such as S from which it can be removed at pleasure. Thus it will be seen that the burners, the scrapers, the auxiliary hoppers, the top of the collecting trough, and the collecting scrapers, are all carried by the carriage.

Referring to Figs. 5 and 6 I will now describe the manner of operating the carriage, and as illustrated in said figures I prefer to operate the machines in pairs. Visa screwthreaded connecting rod extending between the two carriages of a pair of machines. V is an internally screw threaded pulley or double grooved sprocket wheel journaled on a post V and snrroundingthe screw-threaded shaft V. This sprocket wheel is provided with a detachable bifurcated boxing by reason of which it can be removed when worn out and replaced without disturbing the screw-threaded connecting rod between the carriages. v isan endless chain passing from the sprocket wheel to a power sprocket wheel V on the power shaft V. '0 is another endless chain passing from the sprocket pulley V to the pulley of the next pair of machines in case more are employed. WVisa cog-wheel mounted on the power shaftV and engaging in a cog-wheel W having an internally screwthreaded hub through which passes a longitudinally movable screw W provided with tappets 10 which are adapted to engage any of the several known mechanical devices for reversing the engine or motor and make the carriages travel on the reverse movement when the ends of the screw V reach the drive pulley,

By my improved form of machine,I am enabled to secure durability and strength and economy in construction and power of operating.
